Due to the unreasonable development of human beings and the destruction of forests and grasslands on a large scale, the living conditions of humans, animals, and plants have deteriorated. After the loss of forests and vegetation, because of the susceptibility of the soil to erosion, after the erosion of rainwater, landslide events are very likely to occur in mountainous areas, causing damage to mountain roads and even endangering human lives. Therefore, it is very urgent to protect the scarce slopes before the rainy season. Self-drilling soil nailing is a commonly used method of soil reinforcement and is often applied in the foundation repair or construction of earth slopes. The drill can install soil nails at any angle, which is ideal for projects that are difficult to construct, such as hillsides. The installation speed of soil nails is very fast, the use of construction materials is small and the cost is low. It is suitable for large projects such as hillside maintenance. In addition, the mountain road is difficult to walk, many large-scale machinery can not reach the construction site, and the self-drilling soil nail can be installed only with a small robotic arm.
